The Viola is a hollow body.The single pup rivoli has been dropped but they still make the 2 pup version.The Casady sells for around 600.They are superb!Ive had one for awhile now and love it.They are now only available in the gold finnish.Both the burst and ebony are no longer available.Good luck!

Hey guys, I just got back from www.musiciansfriend.com and they have Jack Casady basses in black only for $719.00. They have the Sunburst and The Mettalic Gold listed as
discontinued, but they are notorious for changing
the availability of their products.

I bought one in December after going through the
"discontinued" then "in stock" nonsense for about
10 days. I paid $449.00 for mine.(don't hate me)
If anyone's thinking of getting one, DO IT !
I don't want to rant and rave here, but to put it mildly these basses are way underrated. I wrote a
review of mine in January, but, it's off the forum now. I think you may be able to access it by going into my name, then using the search all posts by this user feature. This bass is unbelievable !
